Abstract

The invention relates to a device for the high-sensitivity resolution detection of an external variable, comprising a substrate, at least one device for generating acoustic surface waves by applying an input frequency, provided on said substrate, at least one active surface, which can be charged with the acoustic surface waves by the generating device, said surface waves interacting with an external variable, and at least one device for receiving the surface waves after they have passed through the interaction field, this device also being provided on the substrate. The surface wave generating device is configured in such a way that the range of propagation of the surface waves in the active surface changes with the input frequency. The invention also relates to a method for the high-sensitivity resolution detection of an external variable. According to said method, acoustic surface waves are sent out over an active area of a substrate and detected. Surface waves of different frequencies pass through other areas of the active surface. The active area is caused to interact locally with the external variable and a change in the parameters of the surface waves is shown by this interaction.
